Hi, I plan to upgrade the rudder-server & i am using self hosted data plane. I got

backend-config	Failed to fetch config from API with error: backend config request failed with 400: {"message":"Invalid workspace token"}

when upgrade the rudder-server. but i confirmed the token is correct. anyone can help?

You need to reset the workspace token, which is obtained from the control plane

Oh how to reset? Is it in the workspace?

reset it in your dataplane, you can observe it via your control plane

To confirm with u, one workspace is connecting to multiple control plane rite? (Sit/dev/prod)

we share it common, please check with your setup and use corresponding token

I don’t get your point. if I reset the workspace shared with dev & prod, does it impact to both setup?

yes thats what will happen.

thanks @most-ocean-90575
